If you're wondering about the value of your miles, it's of no interest what numbers UA's tortured bean-counters are accruing.

Suppose you are planning to use miles for a premium-class long-haul. Then the questions are
a) Cost, how many miles (and how much co-pay in "taxes")
b) Availability for your destination and timeframe

And it's availability that's the killer. Miles earned on a program like Onepass (CO) are effectively worthless if the routes and classes you want are always blacked out.

UA's award availability, and other *A carriers, had been reasonable up to 2007. But this year there's been a sudden culling of award seats, both on UA metal and via UA's Starnet-black-out-algorithm [which blocks the use of UA miles on an increasing proportion of other *A airline award inventory.]

If you had been valuing your miles on the basis of a notional $3,300+taxes for an XC return fare USA to SYD for 110,000 miles that would have been 3c/mile had there been any availability.

There isn't, unless you use the pay-double "standard" award, nothing to SYD thru end of schedule see this thread
